If the Host flutters to the ground, it is unlikely that the individual distributing Communion failed to put it on your tongue; it is more likely that you did not stick your tongue out far enough to get the Host onto it, or that in the process of pulling your tongue back in, you did not have your mouth open enough and the Host hit your front teeth and was flicked off.
And I seriously doubt that anyone hates you,. Some may not appreciate you, but I suspect in your life you have had other people in other circumstances not appreciate you - as is common with everyone I have ever met.
I was an altar boy starting in the 1950’s, and like other grade school children, was not always as “holy” as one might wish for. My classmates and I would talk about how long a ling of spit the priest had pulled from an individual’s mouth periodically. that was usually because the individual receiving did not swallow just before sticking their tongue out, and possibly was someone who salivated strongly. If you wish to receive on the tongue (and this is still the norm in the universal Church), then in order to not cause a problem doing so (as above), stick your tongue out far. And swallow your spit before you do.
Receiving in the hand is an ancient tradition which goes back to the early Church. and continued on into the 10th century. And in the early church, and for a number of centuries, people would receive Hosts to take back to their home (so obviously, they carried the Host back). If you are not comfortable receiving in the hand, certainly feel free to receive on the tongue.
